Costco is scheduled to open a new Wisconsin warehouse on November 25, giving shoppers in Franklin another place to stock up the day before Thanksgiving.
The Franklin store will bring the chainโs bulk groceries and Costco membership perks to a 164,000-square-foot building near South 27th Street and West Drexel Avenue.

A new warehouse and gas station
Costcoโs official Franklin warehouse listing gives the address as 7829 S. 27th St. and lists Wednesday, November 25, 2026, as its opening date.
The project occupies a 20-acre property previously owned by Northwestern Mutual. The City of Franklinโs announcement describes a warehouse at the northwest corner of the intersection, with a 12-pump gas station at the south end of the development and 868 parking spaces.
The gas station will give members another fuel stop in the area. CBS 58 reports that the development is expected to bring more than 100 jobs.
Costco already has southeastern Wisconsin stores in communities including New Berlin, Pewaukee, Menomonee Falls and Pleasant Prairie.
Opening day comes with a holiday wrinkle
Franklin Mayor John Nelson announced an 8 a.m. opening on November 25, according to FOX6 Milwaukee. Shoppers should check the warehouse listing before making an opening-day trip in case the schedule changes.
Shoppers planning a Thanksgiving grocery run should also note what happens the following day: Costco will be closed Thursday, November 26, for the holiday.
The timing puts Franklinโs launch immediately ahead of Black Friday. Costcoโs advertised holiday savings include a November 16โ30 period and a separate November 27โ30 period, with sale dates varying by item and offers available while supplies last.
For residents considering joining, a Gold Star membership costs $65 annually, while Executive membership costs $130 annually, plus applicable sales tax. Executive members can earn a 2% annual reward on qualifying purchases, capped at $1,250; exclusions apply.
Membership also includes a card for one designated household member who is at least 16 and lives at the same address.
Existing members do not need a separate membership for Franklin. Costco says its membership cards can be used at any of its warehouses worldwide.
For holiday purchases, check each itemโs sale window and local availability before heading out. Some of Costcoโs advertised Thanksgiving-week discounts will be underway when Franklin opens, while others are scheduled to begin November 27.
